Yeah, Ash doesn't take kindly to double dating. Youll get the option to apologize and confirm that youre interested only in Ashley, after being honest with her about your previous relationship - Take it. If you continue with Miranda, the above post ^ may happen.

Also - make sure to buy only the "Tennyson Collection" gift for Ash when she's in the hospital. You'll be able to give it to her the second, or third time you see her in the hospital. There are multiple gifts you can purchase at the hospital, but make sure only to buy the Tennyson Collection.
